Bottom / Plug Taps

High quality bottom / plug taps from Outland.

Bottoming / plug taps have a continuous cutting edge with almost no incline. This feature allows a bottoming tap to cut threads to the bottom of a blind hole. A bottoming tap is usually used to cut threads in a hole that has already been partially threaded using one of the other types of tap (taper or second); the tapered end of a bottoming tap is too short to successfully start into an unthreaded hole.
